The usage for Daz and Poser models is roughly the same,.(with a few exceptions) you’re free to make and sell any rendered images, whether that’s still or animated.
Plus,.. Joining the Platinum club gives you free weekly content and hundreds of items at $1.99 .. with big discount on other (non P.C.) items.
for many, the advantage in using a pre-made model is self explanatory, ...it’s a big time saver.
I know there are some issues with Generation 4 figures and the “powerloader” injections / initialisation routine of morph packs which can throw Carrara into a confused heap,. but ,.. if you open DS and load the main figure like V4 . M4 etc,.. and use those Power-loaders to inject all the morph packs,. It set’s up all the morphs and injections,. and after that the main figures should work fine in Carrara.
It sound’s like you’re making your own figures from scratch in a modelling program, then Rigging them in Poser, and loading them into carrara, ......and that’s when it all goes wrong,..
It’s important to remember that although Carrara supports using Poser and Daz3D content, ..that the different owners of Poser, have made changes in different versions, which, in turn, makes it difficult for Carrara, to support ALL poser version figures, ....and still remain Carrara.
quite often you can get around the limitations by importing an older poser figure as a Poser scene file, then saving the figure to Carrara’s browser
Right now,.. P9 and PP2012 have a different weight mapping system to previous poser versions, and any figure built in there, may not work well in anything other than Poser, depending on how you weight map it.
the same applies to Genesis and DS 4.5. where genesis has a different weight mapping, and rigging to previous Daz3D figures.
Not all applications are the same,. and technology advances, so it can become tricky to support ALL possible variations.
But if you want to create and animate your own models, then you can do that in carrara, ..and rigging is easier than in poser (IMO)
